TOP-LIFT HOLDER.

SPECIFICATION forming part of Letters Patent No. 406,184, dated July 2, 1889.

Application filed Mach 2, 1889.

To all whom it may concern.-

Be it known that I, ELIPHALET A. TRIPP, of New Bedford, county of Bristol, State of Massachusetts, have invented an Improvementin Top-Lift Holders, of which the followin g description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide a top-lift plate with top-lift holding mechanism having rocking blocks which are mounted in such manner, as will be described, as to enable the said blocks to bear upon the side edges of a top lift and hold the same in place while being attached to a heel, the'fulcra of the said blocks being movable, to thereby adapt them to top lifts of different sizes.

In this embodiment of my invention the pivoted blocks have their fulcra upon studs or pins of pivoted levers, which are moved in unison by an .actuating plate or device, with which the ends of the said levers engage, the said levers forming carriers for the blocks.

Figure 1 is a top or plan view of a top-lift plate with my improved top-lift-holder mechanism applied thereto, the said plate being partially broken out to represent the usual nail-box below it; and Fig. 2 is a partial side elevation of Fig. 1, the lower part of the nailbox being omitted.

The nail-box A and the top-lift plate B, pivoted thereon at O, are and may be of usual constructionsuch, for instance, as common to the McKay & Bigelow heeling-machine, or substantially as in United States Patent No. 166,795.

The top-lift plate B has applied to it in an adjustable manner a breast-guard a, it, as herein represented, having extended backwardly from it two ears, which, as shown in the drawings, are slotted for the reception of adj usting-screws 8, bywhich the breast-guard may be placed in any desired position. ,Preferably the said ears at their under sides will have splines or feathers to enter grooves 10 in the top-lift plate. (See Fig. 1.) Upon the said plate 13, I have pivot-ed two levers or carriers b I), each carrier having a fulcrum-pin b upon which is pivoted one of a pair of rocking blocks 0, each rocking block being concaved at its inner face to contact with the side edges Serial Ila-301,774. (No model.)

. ofthe top lift near the breast corner thereof, or at a little distance back from the breast. It will be seen that the outer ends of the carriers b b are beveled or inclined, to facilitate the entrance of the top lift between them and into position between the said blocks 0, the latter being, as it will be noticed, mounted to move in recesses formed at the inner sides of the carrier. Placing the blocks in recesses prevents the liability of the breast of the top lift striking against one end of a block while the top lift is being placed in position between the blocks. The ends of the carriers 1) b farthest from the fulcra of the rocking blocks a are made to engage the slides 2 of an actuating-plate cl, herein represented as slotted, as at 3, to receive the ends of the said carriers,

the said plate being shown as guided by two screws 4, extended through the said slide and into the top-lift plate; but the said plate may be guided in any other equivalent manner.

The actuating-plate dis represented as having a pin 5, acted upon by a spring 6, attached to the plate 13, the said spring normally moving the actuating-plate in the direction of the arrow thereon and keeping the rocking blocks 0 pressed toward each other.

In use the operator will push the top lift into position between the said rocking blocks, as represented in Fig. 1, the top lift when being so inserted first coming in contact with the inwardly-beveled ends of the carriers.

I claim- 1. The top-lift plate and the levers or carriers pivoted thereon, combined with the rocking blocks mounted upon the said levers to contact with the side edges of the top lift, and with means, substantially as described, to operate the said levers in unison, substantially as set forth. I

2. The top-lift plate, the levers pivoted thereon, and the rocking blocks carried by the said levers, combined with the spring-actuated plate to engage both of the said levers and move them in unison, substantially as described.

3. The top-lift plate, the levers mounted thereon, and rocking blocks carried by the said levers, combined with the adjustable breast-gage mounted upon the top-lift plate and with means to move the said levers, substantially as described.

the said levers and contained wholly back of the beveled ends thereof, and with a breastgage, to operate substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
